We study the basic reproduction number ( R 0 ) in an epidemic model where infected individuals are initially asymptomatic and structured by time since infection. At beginning of outbreak computation relies on limited data based mostly symptomatic cases, not detected surveillance system. has been widely used as indicator to assess dissemination infectious diseases. Asymptomatic assumed either be...

The spatial heterogeneity on a regional scale of forest biomass is caused by multiple biotic and abiotic factors. However, the contributions factors to remain unclear. Based data National Forest Continuous Inventory (NFCI), digital elevation model (DEM), meteorological Guizhou Province in 2015, we studied aboveground province evaluated contribution rates its influencing using Moran’s I, semivar...

We develop a model to predict optimal diet selection when energy intake varies over consecutive foraging periods. The model assumes that fitness is maximized when the forager maximizes its net reproduction (survivorship x reproduction) over some specified time period. This goal differs from earlier risk-sensitive foraging models which assume that the forager minimizes the risk of failing to sat...

The QESTRAL project has developed an artificial listener that compares the perceived quality of a spatial audio reproduction to a reference reproduction. Test signals designed to identify distortions in both the foreground and background audio streams are created for both the reference and the impaired reproduction systems. Metrics are calculated from these test signals and are then combined us...
